Benefits of technology

[0009]Accordingly, the present invention is to provide an input device that occupies a small volume and is easier to assemble and more durable.
[0014]Accordingly, because the rotary wheel, the sliding base and the circuit board in the input device of the present invention has a low profile, the input device may satisfy the trend for miniaturization. In addition, because the switch in the input device of the present invention is actuated through the sliding motion of the sliding base, the L-shaped actuator in a conventional input device is not required. Hence, the input device of the present invention may be easily assembled and more durable.

Problems solved by technology

However, the conventional input device 100 occupies a rather large volume.
However, shrinking the size of the L-shaped actuator 250 may increase the difficulty of assembling the L-shaped actuator 250 to the space between the movable member 220 and the switch 240 in the production line.
In addition, the L-shaped actuator 250 is more vulnerable to damage when the user exerts too much force.

first embodiment

[0030]FIG. 3 is a schematic perspective view of an input device according to a first embodiment of the present invention. FIG. 4 is a schematic partial explosion view of the input device in FIG. 3. As shown in FIGS. 3 and 4, the input device 300 in the first embodiment is disposed on a circuit board P. The input device 300 includes a frame 310, a sliding base 320, a rotary wheel 330 and a switch 340. The sliding base 320 is slidingly connected to the frame 310. The sliding base 320 substantially slides linearly along a slide axis A1. The slide axis A1 is substantially parallel to the circuit board P. The rotary wheel 330 is revolvably affixed to the sliding base 320. The rotary wheel 330 substantially rotates around a rotation axis A2. The rotation axis A2 is substantially perpendicular to the circuit board P. In addition, the switch 340 is disposed on the frame 310. The rotary wheel 330 actuates the switch 340 through the sliding motion of the sliding base 320.

second embodiment

[0044]FIG. 8 is a schematic perspective view of an input device according to a second embodiment of the present invention. The main difference between the input device 400 in the second embodiment and the input device 300 in the first embodiment is that the switch 440 of the second input device 400 is disposed on the sidewall 412 on the sliding path of the rotary wheel 430 or the sliding base 420. When the rotary wheel 430 slides along the slide axis A1 toward the interior of the frame 410, the rotary wheel 430 slides toward the interior of the frame 410 through the sliding base 420 and the edge of the rotary wheel 430 closest to the sidewall 412 will apply a pressure to the switch 440 to actuate the switch 440.

[0045]FIG. 9 is a schematic top view of the frame in FIG. 8. FIG. 10 is a schematic front view of the input device in FIG. 8. To facilitate the description, some local cross-sections are shown in FIG. 10. As shown in FIGS. 9 and 10, the input device 400 of the second embodime...

third embodiment

[0048]FIG. 11 is a schematic cross-sectional view of an input device according to a third embodiment of the present invention. The main difference between the input device 500 of the third embodiment and the input devices 300 and 400 in the foregoing embodiments is that the switch 540 of the input device 500 may be disposed on the bottom plate 511. Furthermore, the sliding base 520 has a bulge 529 disposed on its bottom surface 526. When the rotary wheel 530 is acted on by an external force along the slide axis A1 toward the interior of the frame 510, the rotary wheel 530 slides into the interior of the frame 510 through the sliding base 520 and the sliding motion of the sliding base 520 causes the bulge 529 to apply a pressure on the switch 540 to actuate the switch 540.

[0049]It should be noted that that bottom plate 511 have a conducting portion 511a and an insulating portion 511b in the present embodiment. The conducting portion 511a is electrically connected to the grounding por...

Abstract

An input device disposed on a circuit board is provided. The input device includes a frame, a sliding base, a rotary wheel, and a switch. The sliding base is slidingly connected to the frame. The sliding base substantially slides linearly along a slide axis. The slide axis is substantially parallel to the circuit board. The rotary wheel is revolvably affixed to the sliding base. The rotary wheel is substantially rotates around a rotation axis. The rotation axis is substantially perpendicular to the circuit board. The switch is disposed on the frame. The rotary wheel actuates the switch through the sliding motion of the sliding base. Accordingly, some merits of said input device include smaller volume, easy assembling and better durability.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an input device, and more particularly to an input device having a sliding type of rotary wheel.[0003]2. Description of Related Art[0004]The user of a mobile phone or a computer screen often makes use of the rotation mechanism of an input device to control a cursor and perform a scrolling, point and click or picture zooming action. The most common input devices include mouse, trackball, joystick and game pad, for example. A user can effectively perform operation through some of these input devices.[0005]FIG. 1A is a schematic perspective view of a conventional input device. FIG. 1B is a schematic perspective view showing some of the components inside the input device in FIG. 1A. As shown in FIGS. 1A and 1B, the conventional input device 100 is disclosed in U.S. Pat. No. 7,075,526. The conventional input device 100 is a mouse comprising a housing 110, a supporting skeleton 120, a roller 1...
